The program ArArCALC provides an interactive interface to data reduction in 40Ar/39Ar geochronology. ArArCALC is coded within Visual Basic for Excel 2000 with the use of datasheets, charts, menus and dialogboxes. All 40Ar/39Ar age calculations are reported in single Excel workbooks.

EC-RAFC is a self-consistent formulation for the conservation of energy, mass and species in a magma body undergoing assimilation and fractional crystallization, with or without recharge in the magma chamber. This Microsoft Excel program tracks the system as magma cools and crystallizes while the wallrock heats up and melts.

ThellierTool 4.0
The program ThellierTool 4.0 provides an intuitive plotting interface to analyze a wide range of different modifications of the Thellier absolute paleointensity experiment. ThellierTool 4.0 is coded within Visual C++ 6.0 and is running on Windows 95/98/ME/NT/2000/XP and was tested on Win2000 and WinME. All calculation results can be saved as tab-delimited text files.

TnT2000 is a MATLAB toolbox for modeling both simple and sophisticated scenarios that mimic the geochemical differentiation of the Earth. In TnT2000, this is achieved by an easy-to-use graphical user interface for defining multiple reservoirs and their intrinsic properties in order to approximate global reservoir geometries, their evolution and the mass fluxes between them.
